IBuyPower and CyberPowerPC have fairly long list and you can pick and choose, but the price will be around $100-200 higher than DIY method and they might not have the exact parts listed above.

Also as a personal comment on Chaud's list... Not getting 250GB SSD is a tragic mistake instead of 120, especially when the budget goes over $1k as it is the biggest quality of life improvement possible.

Never going to log into this garbage forum again as long as calling obvious troll obvious troll is the easiest way to get banned.
Trolling should be.

Its highly recommended to build it, if you can, or know someone who does. As Vesseblah said, you lose anywhere from 100-200 or more on labor, markup, and shipping. I just went to IBuyPower and a pretty much same system (3570K, 8gb ram, 660ti, 240 SSD/ 1tb HD) came out to 1400.

So basically you either need to settle with less parts, or a bigger budget, or build it.
